Total = price per hour x number of hours + travel fee.

Total = 27h + 18

Answer:

X = 16

Step-by-step explanation:

These are supplementary angles, so they equal 180.

5x + 27 + 5x - 7 = 10x + 20

10x + 20 = 180

10x + 20 - 20 = 180 - 20

10x = 160

10x ÷ 10 = 160 ÷ 10

X = 16

Answer:

Correct answer is + or - 6

3/x = x/12

cross multiply

x^2 = 36

x = root 36

x = plus or minus 6

Answer:

6

to solve this. = 3/x = x/12

=}. 3/x = x/12

by doing cross multiple

we get x^2 = 36

so, x=. √36

x=. 6

Answer:

514 m = width of the river to the nearest meter

Step-by-step explanation:

You must memorize the definitions of the trig functions and then these types of problems are easy.

You have a right triangle where the 100 m is the adjacent side to the 79° angle.  You are looking for the side opposite the 79° angle.  So, you need to use the tan function which is defined as opposite side/adjacent side

Let x = the length of the opposite side (width of river)

Tan 79 = x/100

100 tan 79 = x

x = 514 m = width of the river to the nearest meter

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The width of the river is 514.455 meters.

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

Base is the adjacent smaller side of the angle θ.

As it is given that you walk 100 meters to the right of the stake and measure a 79° angle between the stake and the boulder. Therefore, using the tangent angle the width of the river can be written as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}\\\\\\\rm tan(79^o) = \dfrac{\text{Width of the river}}{100\ meter}\\\\\\\text{Width of the river} = tan(79^o) \times 100 = 514.455\ meters[/tex]

Hence, the width of the river is 514.455 meters.

You can slit it into two rectangles. On rectangle would have a area of 2x6 and another rectangle could have an area of 6x3. then you solve the area of the rectangles and add them for the total area. I have a picture of it:

Answer:

30 square feet

Step-by-step explanation:

1. Approach

Break up the given figure into two smaller rectangles. Calculate the area of those two rectangles, and then add up the results.

2. Rectangle 1

The is one extend the line with the measurement of (4ft), then one will get a rectangle with the dimensions of (6ft) and (3ft). Use the formula,

[tex]length * height = area[/tex]

Substitute;

6 * 3 = 18

3. Rectangle 2

The other rectangle that will result from this partitioning will have the dimensions (2ft) and (6ft). Again use the formula,

[tex]length * height = area[/tex]

Substitute,

2 * 6 = 12

3. Find the total area

Add up the area of these two smaller rectangles,

rectangle1 + rectangle2

= 18 + 12

= 30

Answer:

=163.84

Step-by-step explanation:

multiply by 8 on both sides

Answer:

w = 163.84

Step-by-step explanation:

Rewrite the equation as w/8 = 20.48

w/8 = 20.48

Multiply both sides of the equation by 8

8 ⋅ w/8 = 8 ⋅ 20.48

Simplify both sides of the equation.

w = 163.84

Step-by-step explanation:

Answer:

(4) 25​

Step-by-step explanation:

First, find the slope using rise over run:

(y2 - y1) / (x2 - x1)

Plug in the points:

(11 - 5) / (3 - 0)

6 / 3

= 2

The y intercept, (0, 5), has already been given. Using the equation y = mx + b, plug in the slope and y intercept to create the equation:

y = mx + b

y = 2x + 5

Now, plug in 10 as x to find the value of y:

y = 2x + 5

y = 2(10) + 5

y = 20 + 5

y = 25

So, the correct answer is answer choice 4, 25.

The value of the variable 'y' at x = 10 will be 25. Then the correct option is D.

Let the equation of the line pass through (x₁, y₁) and (x₂, y₂).

Then the equation of the line is given as,

[tex]\rm (y - y_2) = \left (\dfrac{y_2 - y_1}{x_2 - x_1} \right ) (x - x_2)[/tex]

A line passes through points (0,5) and (3, 11). Then the equation of the line is given as,

(y - 5) = [(11 - 5) / (3 - 0)](x - 0)

y = 2x + 5

If the value of the variable 'x' is 10, then the value of the variable 'y' is calculated as,

y = 2(10) + 5

y = 20 + 5

y = 25

The value of the variable 'y' at x = 10 will be 25. Then the correct option is D.

Answer:

Step-by-step explanation:

Let's start with the expression 1/(1+i). It is simplified by multiplying numerator and denominator by its conjugate.

  [tex]\dfrac{1}{1+i}=\dfrac{1-i}{(1+i)(1-i)}=\dfrac{1-i}{2}[/tex]

Subtracting this from 1, as in the denominator inside parentheses, gives its conjugate.

  [tex]1-\dfrac{1-i}{2}=\dfrac{1+i}{2}[/tex]

__

The 5th power can be found a couple of ways. One is to use the binomial expansion. Another is to use Euler's formula. The latter can be somewhat easier.

  [tex]\dfrac{1-i}{2}=\dfrac{1}{\sqrt{2}}\angle-\!45^{\circ}\\\\\left(\dfrac{1-i}{2}\right)^5=\dfrac{1}{\sqrt{2^5}}\angle(5(-45^{\circ}))=\dfrac{1}{4\sqrt{2}}(\cos(135^{\circ})+i\sin(135^{\circ}))\\\\=\dfrac{1}{8}(-1+i)[/tex]

With these parts, we can now write the first expression as ...

[tex]\displaystyle\frac{A}{i+i}\left(\frac{1-(\frac{1}{1+i})^5}{1-(\frac{1}{1+i})}\right)=A\left(\frac{1-i}{2}\right)\left(\frac{1-\frac{-1+i}{8}}{\frac{1+i}{2}}\right)=\frac{A}{8}\cdot\frac{1-i}{1+i}\cdot(9-i)\\\\=\frac{A}{8}\cdot\frac{(1-i)^2(9-i)}{1^2-i^2}=\frac{A(-2i)(9-i)}{8\cdot2}=\boxed{-A\frac{(1+9i)}{8}}[/tex]

__

Using the same parts, we can simplify the second expression.

  [tex]\displaystyle\frac{A}{i}\left(1-\left(\frac{1}{1+i}\right)^5\right)=\frac{A}{i}\cdot\frac{(9-i)}{8}=\frac{A(9-i)(i)}{8i^2}=\boxed{-A\frac{(1+9i)}{8}}[/tex]

Answer:

123

Step-by-step explanation:

1 bag = 13 cookies

9 bags x 13 cookies = 117 cookies

117 cookies + 6 cookies that he already has = 123 cookies

Dale have 123 cookies in total.

Answer:

123 cookies.

Step-by-step explanation:

Multiply the amount of bags of cookies he bought, and the amount of cookies in each back to find out the amount of cookies he bought all together.

9 x 13 = 117

He already had six cookies saved. Add that the amount he had bought

117 + 6 = 123

Dale has 123 cookies in total.

Answer:

$11.8

Step-by-step explanation:

Probability of not winning = 1 - 1/50 = 49 / 50

Amount won = 590

X : ____ 590 ___ 0

P(X) : __ 1/50 __ 49/50

Expected payoff :

ΣX * p(x)

(590 * 1/50) + (0 * 49/50)

0.02 * 590 + 0

11.8 + 0

= $11.8
